Title: Improvements relating to radar display apparatus
IPC: G01S1/02
Filed: 1947-01-03
Abstract: 641,420. Radiolocation. MILLER, C. W., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Jan. 3, 1947, No. 274. [Class 40 (vii)] Apparatus for displaying the range and bearing of echoes which arrive at a pulse-radar receiver comprises a light source 1 modulated by the received echoes to produce a beam for display purposes, displacement means, such as rotating spirally-slotted disc 4, for producing recurrent sweeps of the beam synchronized with the operation of the transmitter, and means, such as rotating radially-slotted disc 3, for displacing the beam angularly in accordance with the direction of the aerial. Disc 4 mav be rotated at a speed high compared with that of disc 3 whereupon the intersection of slots 9 and 7 causes the light beam to execute recurrent radial sweeps, successive sweeps being angularly displaced so as to produce a plan-position display. Synchronism with the transmitter is maintained by photocell 12 which sends a signal to the transmitter each time apertures 13 and 14 are aligned with lamp 11. A spiral time-base may be produced by rotating the radial slot at the higher speed. Two curved slots may be rotated in opposite directions to produce a radial time base which is caused to rotate by suitably choosing the speed difference. By suitable choice of slot shape, linear or non- linear time bases may result; disc 4 may have more than one spiral slot, each slot covering a separate sector. A time base progressing radially inwards may provide expanded indication of short-range echoes. Alternative suitable displacement means are mirror drums or deflector prisms which are moved to provide the radial sweeps and are mounted on a rotatable carrier.

Title: Time division multiplex telecommunications systems
IPC: H04M7/00
Filed: 1974-01-07
Abstract: 1459865 Automatic exchange systems SIEMENS AG 7 Jan 1974 [5 Jan 1973] 00653/74 Heading H4K A tdm system includes at each end of a signalling channel a D.C. to pulse and a pulse to D.C. characteristic converters U2, U1 arranged as a pair and which are associated with a subscriber end input E and a subscriber end output A via an arrangement of four relays C, R, I, II, associated respectively with contacts C1, C2, r, 1, 2, a power supply B, a delay element VG and a diode D, the interconnections being substantially as shown in Fig. 1. The position of the switches is shown for the unoperated state of the corresponding relay. The arrangement is used to enable the signalling channel to be seized either by exchange ES1 or ES2 and the specific arrangement of components in each station is for signalling the conditions "ready for seizure", "seizure" and "reverse blockage". Signalling between converters uses four bit binary signals but for signalling the above conditions only bits 1 and 4 are significant, bits 2 and 3 being "1" for all the conditions. In a ready for seizure state relay R is operated to apply earth to input UE2 via contact r. The condition 1110 is transmitted and earth at output UA2<SP>1</SP> operates relay II<SP>1</SP> to close contact 2<SP>1</SP>. The same condition exists in the reverse direction to hold relay II operated and contact 2 closed. To seize the channel from exchange ES input E is earthed to operate relay C. Contact C2 opens immediately removing the earth from input UE2. The condition 1111 is transmitted to cause output UA2<SP>1</SP> to go to 1 thereby releasing relay II<SP>1</SP> to open contact 2<SP>1</SP>. The channel cannot then be seized by exchange ES2. In exchange ES1 the closure of contact C1 on the operation of relay C causes earth to be applied to input UE1 after a delay determined by element VG. Condition 0111 is then transmitted causing output UA1<SP>1</SP> to go to earth to operate relay I<SP>1</SP>. Output A<SP>1</SP> is then connected directly to earth via contact 1<SP>1</SP> and relay R<SP>1</SP> releases thereby removing the earth on input UE2<SP>1</SP>. Condition 1111 is transmitted from exchange ES2 to exchange ES1 as an acknowledgement of seizure signal. Relay II is however held via diode D when the earth is removed from output UA2 on receipt of the 1111 signal. Similar operations take place when release occurs due to the removal of the earth mark or input E. It is stated that the relays may be replaced by corresponding electronic switching elements.

Title: Improvements in or relating to moving coil pickups
IPC: H04R9/16
Filed: 1940-01-12
Abstract: 538,058. Gramophone pick-ups. VOIGT, P. G. A. H. Jan. 12, 1940, No. 757. [Class 40 (iv)] In a pick-up in which the coil does not embrace a stationary part of the magnetic circuit, an elongated coil wound lengthwise is supported by self-positioning means, such as by clamping or bedding in resilient material, the coil being operated (1) by rotary vibration about an axis close to which the conductors lie, or (2) by bodily movement for use with hill-anddale records, or (3) by both (1) and (2) for combined lateral cut and hill-and-dale records. The coil former may consist of a central lamination A, Fig. 1, and two side laminations B combined as at C to leave a projecting strip around which aluminium wire is wound lengthwise. The coil is surrounded by two rubber' rings F or by a continuous rubber sheet and mounted in the magnet gap so that it can rotate for lateral-cut records or move bodily in the gap for hill-and-dale records. To improve visibility of the needle and reduce magnetic leakage when a ferrous turntable is used, the magnetic system may comprise block magnets and sloping pole-pieces, Fig. 4 (not shown). In a modification, the coil may be mounted on one side of the lamination as shown in Fig. 5 (1), part of the coil lying outside the magnetic field as shown in Fig. 5 (2). Two coils mounted in this way may be connected in series and parallel as shown in Fig. 5 (3) to two transformers, so that voltages corresponding to lateral cut may be obtained from the upper transformer and to hill-and-dale cut from the lower transformer. The laminations A, B, Fig. 1, may be of magnetic material.

Title: Improvements in and relating to mountings for reciprocating engines
IPC: B60K5/12
Filed: 1932-01-12
Abstract: 399,161. Mounting motors &c. CHRYSLER CORPORATION, 341, Massachusetts Avenue, Detroit, Michigan, U.S.A. Jan. 12, 1932, No. 888. Convention date, June 6, 1931. [Class 79 (iii).] A reciprocating engine is supported by resilient means, such as rubber pads 12, 17, located fore-and-aft, allowing the engine to oscillate with substantial freedom about a longitudinal axis passing through its centre of mass 26. The axis may be inclined downwardly from front to rear, as shown at 27, and may intersect the transmission axis at or near the coupling 25 between the crank shaft and the main drive shaft 7<1>. The pads 12, 17 are shown carried by cross - members 2, 3 of a motor vehicle frame, the front pad 12, which is angular in form, being seated on a triangular bracket 8 and supporting a flange 11 projecting from the crank case, whilst the rear pad 17 is of arcuate form concentric with the crank shaft, Fig. 4. The pads are preferably bonded as by vulcanization, the pad 12 to attachment plates 13, 14, adapted to be bolted to the bracket 8 and flange 11 respectively, and the pad 17, between a channelled bracket 19, bolted to a flange 21 protruding from the transmission housing 22, and a correspondingly arcuate shaped bracket 23 bolted by means of a flange 24 to the cross-frame member 3. The pads, while allowing substantial freedom of oscillation about the axis 27 and serving thus to dissipate torque reaction impulses tending to rotate the engine about such axis, offer much greater resistance to vertical movements of the engine under the influence of the piston reciprocations. In order to keep the natural frequency of oscillation about the longitudinal axis below the working frequency of the torque reaction impulses, to avoid risk of synchronization, angular displacement resisting apparatus may be provided comprising a flexible or rigid arm 28 disposed between the engine and the chassis frame and having an end located by resilient means, such as a rubber block 32, and with or without a yielding means or stop 34, for limiting the oscillation of the engine in a direption counter to torque reaction impulses. The resilient arm 28 may be biassed to hold the transmission housing 22 against the stop 34 when the engine is inoperative. Specifications 399,168 and 399,169 are referred to.

Title: Selective oxidation of graphite from mixture thereof with diamond
IPC: B01J3/08
Filed: 1965-05-19
Abstract: A process for selectively oxidizing graphite in a mixture thereof with diamond comprises heating the mixture with a lead oxide or lead oxide precursor at a temperature sufficiently high to achieve oxidation of the graphite and sufficiently low to avoid substantial oxidation of the diamond, said temperature being within the range of 350 DEG  to 550 DEG  C., preferably 380 DEG  to 430 DEG  C. in the presence of air or oxygen.  The oxidation catalyst may be PbO, PbO2, Pb2O3 or Pb3O4, or mixture thereof or an oxygen-containing lead compound which is transformed to a lead oxide in situ, e.g. lead carbonate, hydroxide, nitrate or subacetate.  The graphite particle size is preferably less than 1 mm., especially less than 200 microns and the lead compound particle size is preferably less than 1 mm., especially less than 50 microns, and the catalyst and graphite should preferably be intimately mixed.  Preferably 5% of lead oxide catalyst, based on the weight of the graphite-diamond mixture, and more preferably 10% to 100%, may be used and oxidation may be carried out merely in an atmosphere of air or oxygen, or air or oxygen may flow through and/or over the mixture which may be shaken or swirled. After oxidation of the graphite the diamond may be recovered by selectively dissolving out the lead oxide with an aqueous acid such as nitric, acetic, hydrochloric, citric or ethylenediaminetetraacetic acid.

The material-to-betreated is introduced through pipes 31 or 35. The liquid or granular solid product is withdrawn through pipe 30. Gas or vapour flows from separator 24 into cyclone 36 and then into compressor 37; and some of the compressed gas or vapour is introduced into section 21 below perforated tray 26. Another portion of the compressed gas or vapour is conducted into the shell of heat exchanger 22 as heating medium. The outer surfaces of tubes 27 are provided with flanges over which any condensate of the heating medium flows in films, thereby increasing heat transfer. Graphite may be applied to the inner walls of the apparatus. Excess gas or vapour is discharged via valve(s) 39. Chamber 23 contains a vibration-generator 81. The apparatus may be used as a boiler for a distillation column, as in Fig. 11, where reference 75 indicates the heat-exchanger, and the distillation column 79 is connected to the separation chamber 77.

Title: Circuit arrangement for the automatic adjustment of the steady current in a push-pull end stage
Inventor: SCHMITZ FRIEDRICH
IPC: H03F1/32
Filed: 1996-01-25
Abstract: 2.1 The quiescent current of a push-pull output stage is automatically adjusted by providing a sensing element in each branch of the output stage. The two voltages measured across the sensing elements with respect to reference potential are input to a differential amplifier stage, the output voltage of which is compared with a reference value with the aid of a comparator. The circuit exhibits a frequency-dependence of the automatic quiescent-current regulation due to the cut-off frequency of the output transistors used. 2.2 To avoid this frequency-dependence, a phase-rotating section is connected to one input of the differential amplifier, which worsens the common-mode suppression of the differential amplifier at high frequencies. The result of this measure is that the frequency- dependent error is compensated. 2.3 Push-pull output stages with quiescent-current control. <IMAGE>

Title: Ornamental chain
Inventor: BUNZ GEORG
IPC: A44C5/10
Filed: 1995-03-30
Abstract: An ornamental chain consists of a core made of at least two parallel or twisted strings (11, 12, 13) and at least one metal wire (10) passing around said core, essentially punctiform contact surfaces (K) being formed between each string (11, 12, 13) and the metal wire (10). As a result, a very "free" fastening of the peripheral metal wire (10) is achieved by the core, and the bending behaviour of the peripheral metal wire (10) is very even due to the multi-point fastening by the continuous strings (11, 12, 13). The strings are preferably formed from metal or a metal alloy so that a high mechanical stability of the core can also be achieved.

Title: Disk drive controller
Inventor: SANDER WENDELL
IPC: G11B20/10
Filed: 1992-09-24
Abstract: A disc drive controller has read post compensation which corrects for peak shift effects on discs with insufficient precompensation. The data is recorded in Manchester (MFM) format and read into circuitry including SCT counter (451) which loads parameters representing a cell with a short-cell (2 unit) following it and LCT counter (453) which loads parameters representing a cell with a long cell (3 or 4 unit) following it. Bound detector 455 counts the number of pulses between transitions and shift registers (457, 459) store the number of pulses generated by the respective counters to enable the bound detector to generate peak shift compensated pulses. The controller has a programmable parameter scheme which makes it possible to read and write 3 1/2 inch variable and fixed speed drives, as well as standard 5 1/4 inch drives. Additionally, there is a plus/minus rate multiplier to correct for symmetry and frequency errors. The use of half clock circuits to provide half clock resolution in the signal being written to and read from the disk is provided with the capability of operating at continuously variable clock speeds and data rates dynamically programmable by the computer. <IMAGE>
